provide data that is directly applicable to human populations, but ten or more
y
ears follow-up may be needed to provide answers about some health effects,
such as cancer. This is because the interval between the time of exposure to
a cancer-causing agent and the time tumors develop — if they do — may be
many, many years. The interpretation of epidemiological studies is hampered
by difficulties in measuring actual RF exposure during day-to-day use of
wireless phones. Many factors affect this measurement, such as the angle at
which the phone is held, or which model of phone is used.
6. What is the FDA doing to find out more about the possible
health effects of wireless phone RF?
The FDA is working with the U.S. National Toxicology Program and with groups
of investigators around the world to ensure that high priority animal studies
are conducted to address important questions about the effects of exposure
to Radio Frequency (RF) energy.
The FDA has been a leading participant in the World Health Organization
International Electro Magnetic Fields (EMF) Project since its inception in
1996. An influential result of this work has been the development of a
detailed agenda of research needs that has driven the establishment of new
research programs around the world. The project has also helped develop
a series of public information documents on EMF issues. The FDA and the
Cellular Telecommunications & Internet Association (CTIA) have a formal
Cooperative Research And Development Agreement (CRADA) to do research
on wireless phone safety. The FDA provides the scientific oversight, obtaining
input from experts in government, industry, and academic organizations.
CTIA-funded research is conducted through contracts with independent
investigators. The initial research will include both laboratory studies and
studies of wireless phone users. The CRADA will also include a broad
assessment of additional research needs in the context of the latest research
developments around the world.
7. How can I find out how much Radio Frequency energy
exposure I can get by using my wireless phone?
All phones sold in the United States must comply with Federal
Communications Commission (FCC) guidelines that limit Radio Frequency
(RF) energy exposures. The FCC established these guidelines in consultation
with the FDA and the other federal health and safety agencies. The FCC limit
for RF exposure from wireless phones is set at a Specific Absorption Rate
